TO ALL WHOM IT MAY-OONCERN:

Be it known that THOMAS LEESON, of Sharon, in the county of Walworth, and State of Wisconsin, have invented n. new and useful improvement in Post Auger; und I do hereby declare that the following is :t full, cleur, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a top View of my improved auger, the slm-nk being eut of? through the line y y, fig. 2.

Figure 2 is :t side View of the samekpartly in section, through the lille x x, lig. 1.

Similar letters 'of reference indicate like parte.

My invention has for its object to furnish un improved auger for boring post holes, simple in construction und effective in operation; and it consists in the combination of the spiral spring-plate and adjustingfnuts with euchA other and with the 4shank of the auger, es hereinafter more fully described.

is the shank, the upper end of which is made branched for the more convenient attachment ofthe handle B. The lower end of the shank A is meile pointed, to more 'easily enter the ground, und to steady the auger while boring itsway into the ground. C is the spring-plate. which is made of such a. length as to pass n little more than once around the slmnk. The shank A passes through holes in the ends of the plate, or in arms formed upon or attached to seid plate. The hole in thelower end of Suid spring-plate has u screwthread cut in it tting upon u screw-thread eut upon the lower part 'oi' the shank A; the hole through the upper end is of such a size that it can move freely up und down over the screw-threads upon the shuhk A. l) und E are nuts fitting upon the screw-thread ofv the shank A, und which are placed the one above and the other below the said 'pl-(ite so as to clamp the upper end of said plete securely in :my desired position. This construction enables the ends of the plate C to be se'trnn'd secured at any desired distance apart, and enables the feed of the saw to be adjusted nt' pleasure ziccording to the' charuet-erbf the zground in which the hole is being bored. F is a lip formed upon or lttuehedto the outer 'edge of the upper part of the plate C, and extending down nearl)y to the other end of the said platte to separate the ground loosened by the a-dvaneeof the forward end of the plate so as to leave a smooth interior surface to said holle.

I claim es new, und desire to seeure by Letters Petenti The combination of the spiral springplate C und nuts D and E with each other und with the slntnk A, substantially as herein 'shown end deseribed -and for the purpose set forth. y
